SASH-FASTEN ER.

SPECIFICATION forming' perfor Letters Patent No. 606,484, dated ,time 28,1898.

Application filed October l, 1897.

To a/ZZ whom, it may concern:

Be it known that I, JOHN GREIFE, of Dayton, in the county of Campbell and State of Kentucky, have invented a new and Improved Sash-Lock, of which the following is a full, clear, and exact description.

This invention relates to an ilnprovement in sash-locks, and has for its object toeprovide a novel device of the class mentioned, which is of simple and inexpensive construction, is readily applied to a window without cutting the easement or sashes, and which when in operative position on a window-easement is adapted by lmanipulation of one part of the dev-ice to simultaneously lock both sashes against sliding movement, and also prevent either sash from rattling when in a locked condition.

The invention consists in the novel construction and combination of parts, as is hereinafter described,and defined in the appended claims.

Reference is to be had tothe accompanying drawings, forming a part of this specification,

in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a transverse sectional elevation of a window-easement and upper4 and lower elevation of a portion of a window-easement and of the complete sash-lock therein. Fig. 3 is an inner edge view of the easement portionshown in Fig. 2 and of the sash-locking device thereon seen in direction of arrow in Fig. 2. Fig. Liis a transverse sectional view.

inward displacement. The usual partingstrips, such as A2, secured at each side of the peripherally projects a finger-piece 10a. In the convex edge of the block 10 a leather or gum facing 11 is embedded, said facingbeing also "convexly curved on the outer edge, that projects somewhat beyond the periphery of the block, as clearly shown in Fig. 2.

` Anl aperture is formed in the block 10 at a point near the edge and is so positioned that the convex curved edge of the facin g11 will be eccentric thereto. At a suitable distance from said aperture in the block 10 the latter is perforated to receive the lower end cof a connecting-rod 12, which is bent 4at Va right angle to loosely occupy said perforation. The eccentric block 10 is secured uponthe side of the bead-strip A by a pivot-screw 413,which screw passes through the aperture of the block provided to receive it, and the eccentric block is thus loosely held in position at a proper distance from the top cross-bar of the lower sash C.

The upper end of the Vconnecting-rod 12 is bent laterally to form apivot or journal end b, and said end loosely enters a transverse perforation formed in one'limb of the hellcrank lever 14, which consists of an essentially triangular block laterally perforated near each of its three angles.

The perforation in the limb of the lever 14 substantially opposite the limb loosely engaged by the pivot end of the rod 12 receives lthe bent pivot end of a pusher-bar 15. On the opposite end of the bar 15 a presser-block 16 is screwed, and thus is adjustably held thereon.

The presser-block 16 has preferably aL gum facing-piece 16a secured on the end'opposite that penetrated by the threaded end ofthe pusher-bar 15, and said block 16 is of a suffi- IOO cient area at the end having said flattened facing to adapt the block and facing for eficient service, as will presently be described.

In the perforation in the triangular block or bell-crank lever 14, above and between the limbs of the block wherein the rod 12 and bar are pivoted, a pivot-screw 17 is inserted and passes into the upright bead-strip A, as shown in Figs. 2, 3, and 4.

The length of the connecting-rod 12 is so proportioned that when the eccentric block 10 is suitably positioned on the bead-strip A', so as to be adapted by partial rotation in a downward direction .to forcibly contact the gum facing 11 with the adjacent vertical side bar of the lower sash C, then the presser-block 16 will be projected towarda like bar on the upper sash B to hold both sashes from sliding movement,it being understood that the sashes lare both closed when such an adjustment of the locking device is effected.

On the bell-crank lever 14 a projection c may be formed below and near the pivoted end of the pusher-bar 15, which projection y is adapted to prevent the pusher-bar and presser-block 16 from falling below a horizontal plane, but will permit the parts mentioned to be rocked-upwardly and away from the sash B, so as to rest, as indicated by dotted lines in Fig. 2, on a stop or projection d.

It will be seen that a downward vibration of the finger-piece 10, which will force the facing 11 into locking contact with the inner side of the lower sash C, will simultaneously Furthermore, it will be seen that the sashes B O may be locked at any point of sliding adj ustment given thereto by the improvements, and also that when the sashes are closed and locked they will be pressed against the beadstrips and parting-strips of the window-case- Inent withy such force as will prevent either sash from rattling.

In applying the improvement for service it is preferred to provide the same in duplicate for a window and secure the two fasteners on the inner bead-strips of the window-casemcn t,

so that the sashes may be held together and against the bead-strips in a manner which will prevent dust or air from entering the room between or around the sashes. This provision will so effectually seal all crevices around the window-sashes that the need of weatherstrips will be obviated.

Having thus described my invention, I claim as new and desireto secure by Letters Patent- 1. In a sash-lock, the combination with an eccentric block pivoted to lock the lower sash, of a pivotally-supporte'd bell-crank lever, a pusher-bar loosely held on and projecting from the bell-crank lever, a presser-block on the pusher-bar, and a connecting-rod loosely engaged at its ends with'the eccentric block and bell -crank lever, substantially as described.

2. In a sash-lock, the` combination with a` rockable friction-block adapted to lock the lower sash, of a pivoted bell-crank lever above said rockable friction-block, another frictionblock on a pusher-bar which is rockable on a limb of the bell-crank and thus adapted for projection toward the upper sash to lock it, means to connect the bell-crank and lower friction-block for their simultaneous rocking movement, and a projection on the bell-crank for support of the upper friction-block when it is rocked away from the upper window-sash, substantially as described.

3. In a sash-lock, the combination with an eccentric block having a finger-piece, and a gum facingheld to project from the periphery of the eccentric block, said block being eccentrically pivoted upon a bead-strip of the window-easement adjacent to the lower sash of the window, of a bell-crank leverpivoted, bev tween two opposite limbs, on the bead-strip above the eccentric block, a connecting-rod IOO
